GridView.count() not working inside a Column Widget-Flutter

Question

When i am trying to use GridView.count() to build the body under 'Skills' ,as shown in the design, Its not working i.e the gridview is not visible at all. I understood it might be due to I am using it inside a Column, and a suggested solution was wrapping it with an Expanded widget, but it didn't work too. It gave 'Incorrect use of ParentDataWidget' error then. So can anyone help me fix this problem?

The related part of the code :

Widget _buildAboutView() {
    return SingleChildScrollView(
      child: Column(
        children: [
          AboutTile(
            title: 'Bio',
            child: Text(
              'I’ve always had a natural curiosity for machinery. As a child, I loved taking things apart and putting them back together. By the age of 12, I was building components for use in construction and even making a bit of pocket money for my troubles.',
              softWrap: true,
            ),
          ),
          AboutTile(
            title: 'Skills',
            child: Container(
              height: 100,
              child: Expanded(
                child: GridView.count(
                  crossAxisCount: 4,
                  shrinkWrap: true,
                  physics: NeverScrollableScrollPhysics(),
                  children: [
                    SkillsBlock(title: 'Web Design'),
                    SkillsBlock(title: 'JavaScript'),
                    SkillsBlock(title: 'HTML'),
                    SkillsBlock(title: 'HTML'),
                    SkillsBlock(title: 'HTML'),
                    SkillsBlock(title: 'Web Design'),
                  ],
                ),
              ),
            ),
          ),
          Divider(
            color: AppTheme.black20,
          ),
        ],

Use Wrap instead of GridView with chip widget for decoration.

AboutTile(
  title: 'Skills',
  child: Wrap(
    children: [
      Chip(label: Text('Web Design')),

Try Wrap like so:

 AboutTile(
   title: 'Skills',
   child: Container(
    child: Wrap(
     children: [
      SkillsBlock(title: 'Web Design'),
      SkillsBlock(title: 'JavaScript'),
      SkillsBlock(title: 'HTML'),
      SkillsBlock(title: 'HTML'),
      SkillsBlock(title: 'HTML'),
      SkillsBlock(title: 'Web Design'),
    ],
   )
  ),
),
